To advance the synthesis of nano-crystallite gahnite, this article reports the effect of solution pH on the gel combustion performance and the final gahnite particle characteristics. The gels were prepared at different pHs, 2.5–10.5, and the obtained precursors were calcined at four temperatures, ranging 600–1200°C. DTA-TG, XRD, BET and TEM were employed to characterize the combustion process and...
